Model T Ford Forum: Magnet Recharger Magnet Recharger:: Magnet Recharger By on Sunday, February 19, 2012 - 11:39 am: I would like to have my own magnet recharger and am wondering what would be a good one to look out for. I would also like to see pictures and descriptions of operation that forum members have. Got anything Jay? Has there been an article on magnet recharging in one of the club magazines? By on Sunday, February 19, 2012 - 12:27 pm: Randy, It is very easy to make a magnet charger. Here is the most simple: Other types: And very crude but also very effective charger: Jim By on Sunday, February 19, 2012 - 01:34 pm: Jim, those coil pole pieces have to make full contact with the magnet end for a good charge that will to produce the maximum flux transfer. They can only do that if they are free to move a limited amount to make a complete contact.
You will also produce a stronger flux transfer if the magnet ends and pole ends are very smooth. You also must connect a south pole of your magnet to the north pole of your charger and ensure that one of those poles on your charge is north and the other one is south. If not the wires on one of the coils must be reversed.
Gingery sells a good HOW TO book on building a Magnet Charger for about $5. He can be found at along with a list of many other books. One thing that David\'s charger lacks is a way to slope the poles 11.25 degrees to mate up closer to the Model T Magneto magnet ends.
David\'s charger is a close copy of one manufactured by Joseph Weidenhoff in Chicago for many years. The major difference is that Joes\' charge included an AC Rectifier circuit and plugged into house current receptacles. David\'s charge uses a battery.
Here is an original Joseph Weidenhoff charger photo. The rectifier circuit is in the rear and not shown.

I use a service station battery charger to connect to the charger and get the guys magnets to 4 pounds. I lay my magnets flat but maybe Ron Paterson can tell us which method works best.

Jim By on Sunday, February 19, 2012 - 03:22 pm: Lowell Spicer first told me about the Gingery Magnet Charger and the need for the 11 degree offset to make a good contact with the magnet poles. He just hold the magnet above the pole pieces and presses the button for current. The poles align correctly and automatically. A slight adjustment might be required for a maximum contact area and a couple more short button pushes completes the charge routine, unless a few short taps with a brass hammer are added to get full benefit. This is Lowell\'s unit that was built from Dave Gingery\'s plans. It plugs into an AC supply, like the Weidenhoff original charger.
